Hi,
I need to move this SAN disk from one host to another. The destination host does not have any VG/VOL setup.
The disk is "emc1_0a39" contains..
subdisk: emcvmax4-01
plex: logs720-01
volume: logs720

The disk emcvmax4 ( emc1_0a39 ) has volume ( logs720 ), plex ( logs720-01 ) and subdisk ( emcvmax4-01 ).
The disk is not part of any other volume or Disk group
Need to move disk along with all volume information and data to another host
The disk is part a the Disk group diskgroup001. But the Disk group diskgroup001 and other disks in the Disk group diskgroup001 will not be moved. So cant use DEPORT\IMPORT Disk group
Will a disk offline do the job after umounting the vxfs filesystem, will all the data and Veritas volume info (priv region) move across when the disk is presented to the other host?

Hi,
If you have the Enterprise license, then you could look to use the Disk group split feature. This can be used to split off the disk to its own diskgroup on the source server (There is also a join feature).
On the second system, you will need a compatible SF version installed, and the disk/LUN will need to be visible.
Then it should be a case of unmount & deport on the source system and a rescan & import on the second system

Here is the section in the docs on Disk Group split

Hello ,
VERITAS Storage foundation is totally Platform-independant , if you map the LUN to any other host with regards to the SF version then you would be able to import the disk group to the other host with no problems at all as the private region exist on the disk itself not on the operating system
In case you do not want to deport and import the disk group. The only way to do it is to clone the LUN on the storage level , then map the clone to the other host then import the diskgroup on the new host.

What if you don't have enterprise? Is it still possible?

You can use keyless licencing to give you the diskgroup split and join feature as an eval for 60 days and then you can remove keyless licence after diskgroup is split
So:
Once you have split of diskgroup, then to remove keyless licencing:
# vxkeyless set NONE
